I am thinking about getting a crested gecko at Repticon Atlanta tomorrow, but I need some input on the housing situation. I currently have two extra 16x16x20 screen cages, a 12x12x18 Exo Terra, and several ten gallons. Which of those would work best for a juvenile crestie? Of course I'll buy a bigger enclosure when the time comes, but for now I'd hate for these extra enclosures I already have to just sit around empty. I just can't decide which one. I feel like I need to use glass for humidity purposes, but the screen cages just have so much more room for running and jumping. Opinions?
